A mere 20 years after the Treaty of Versailles had supposedly closed the "war to end all wars," the world was consumed once again, though by a far more devastating conflagration. World War II was the first major conflict to claim more civilian lives than it did soldiers, ultimately sentencing more than 50 million people to death. This visual history is the second in a series chronicling wars of global significance, informed by period reports and eyewitness accounts and illustrated with hundreds of captioned photographs from the archives of London's Daily Mail, one of Britain's leading newspapers since the turn of the 20th century.
